Dishwasher with condensing drying system

ABSTRACT

A dish treating appliance for treating dishes according to a cycle of operation can comprise a tub defining a treating chamber. The treating chamber can fluidly couple to condenser having an inlet, an outlet, and a condensing passage. The condenser can further comprise multiple ambient air inlets to mix humid air drawn from the treating chamber with ambient air within the condenser. The condenser can further integrate a water inlet with a condenser outlet, such that a water supply and condensed liquid can be provided to the treating chamber through the same opening.

BACKGROUND OF THE INVENTION

Automatic dishwashers for use in a typical household include a tubdefining a treating chamber and a spraying system for recirculatingliquid throughout the tub to remove soils from the dishes and utensils.Two common configurations are a door-type, where a pivoting doorprovides access to a treating chamber where dishes are washed or adrawer-type where a drawer provides access to the as well as defining amajor portion of the treating chamber. In either configuration, a rackfor holding dishes to be cleaned is typically provided within thetreating chamber.

Typical automatic dishwashers generally include a drying cycle which caninclude heating the treating chamber to evaporate a part of liquid usedto wash or rinse the dishes and can include a condenser to furtherremove humidity from the humid air within the treating chamber. Typicalcondensers highly depend on the temperature difference between the humidair and the condenser walls. A reduction in this temperature differencereduces condenser efficiency. Furthermore, typical condensers require anadditional conduit and inlet to provide a condensed liquid back to thetreating chamber for removal by the pump.

Further still, some automatic dishwashers can allow an amount of steamto escape through inlets such as a water inlet. The escaping steam candamage internal components or soak an internal sound blanket, requiringwatertight sealing or plastic wrapping to preventing water damage fromthe escaping steam.

The second lower spray assembly 26 is illustrated as beinglocated adjacent the lower dish rack 22 toward the rear of the treatingchamber 16. The second lower spray assembly 26 is illustrated asincluding a vertically oriented distribution header or spray manifold52. Such a spray manifold is set forth in detail in U.S. Pat. No.7,594,513, issued Sep. 29, 2009, and titled “Multiple Wash ZoneDishwasher,” which is incorporated herein by reference in its entirety.

A recirculation system is provided for recirculating liquid from thetreating chamber 16 to the spray system. The recirculation system caninclude a sump 40 and a pump assembly 42. The sump 40 collects theliquid sprayed in the treating chamber 16 and can be formed by a slopedor recessed portion of a bottom wall of the tub 14. The pump assembly 42can include both a drain pump 44 and a recirculation pump 46. The drainpump 44 can draw liquid from the sump 40 and pump the liquid out of thedishwasher 10 to a household drain line (not shown). The recirculationpump 46 can draw liquid from the sump 40 and the liquid can besimultaneously or selectively pumped through a supply tube 50 to each ofthe assemblies 24, 26, 28, 30 for selective spraying. While not shown, aliquid supply system can include a water supply conduit coupled with ahousehold water supply for supplying water to the treating chamber 16. Aheating system including a heater 54 can be located within the sump 40for heating the liquid contained in the sump 40 or heating thedishwasher during a drying cycle, for example.

A condenser 60 can be provided between the chassis 12 and the tub 14,extending along a portion of the tub 14. The condenser 60 can mount tothe chassis 12 or the tub 14, such as by fastening with fasteners or bywelding. A condenser inlet 62 can provide fluid communication betweenthe treating chamber 16 and the condenser 60. A condenser outlet 66 isexemplarily provided near the bottom of the dishwasher 10 for exhaustingair from the condenser 60 external of the dishwasher 10.

A controller 70 can also be included in the dishwasher 10, which can beoperably coupled with various components of the dishwasher 10 toimplement a cycle of operation. The controller 70 can be located withinthe door 18 as illustrated, or it can alternatively be located somewherewithin the chassis 12. The controller 70 can also be operably coupledwith a control panel or user interface 72 for receiving user-selectedinputs and communicating information to the user. The user interface 72can include operational controls such as dials, lights, switches, anddisplays enabling a user to input commands, such as a cycle ofoperation, to the controller 70 and receive information.

As illustrated schematically in FIG. 2, the controller 70 can be coupledwith the heater 54 for heating the wash liquid during a cycle ofoperation, the drain pump 44 for draining liquid from the treatingchamber 16, and the recirculation pump 46 for recirculating the washliquid during the cycle of operation. The controller 70 can be providedwith a memory 74 and a central processing unit (CPU) 76. The memory 74can be used for storing control software that can be executed by the CPU76 in completing a cycle of operation using the dishwasher 10 and anyadditional software. For example, the memory 74 can store one or morepre-programmed cycles of operation that can be selected by a user andcompleted by the dishwasher 10. The controller 70 can also receive inputfrom one or more sensors 78. Non-limiting examples of sensors that canbe communicably coupled with the controller 70 include a temperaturesensor and turbidity sensor to determine the soil load associated with aselected grouping of dishes, such as the dishes associated with aparticular area of the treating chamber.

Turning to FIG. 3, the chassis 12 is illustrated as having a side panelof the chassis 12 removed, better illustrating the condenser 60 mountedto the side of the tub 14. A drain conduit 86 is mounted by mounts 88adjacent to the condenser 60. The condenser 60 runs along the side ofthe tub 14 and curves underneath the tub 14 to couple to the condenseroutlet 66.

Best seen in FIG. 4, the condenser 60 comprises an inlet section 100coupled to a condenser conduit or a condensing passage 102. Thecondensing passage 102 comprises a first ambient air inlet 104, a secondambient air inlet 106, and a siphon break 108. A water supply conduit110 and an exhaust conduit 112 couple to the bottom of the condenser 60opposite of the inlet section 100. The exhaust conduit 112 couples thecondensing passage 102 to an outlet 116 through a blower housing 114.The blower housing 114 can comprise an exhaust mixing conduit 118disposed between the blower housing 114 and the outlet 116.

The inlet section 100 fluidly couples the treating chamber 16 to thecondensing passage 102. Additionally, the first and second ambient airinlets 104, 106 provide fluid communication between the condensingpassage 102 and an ambient air supply, external of the condenser 60 andthe treating chamber 16. The water supply conduit 110 can provide aliquid supply, such as a water supply, to the condenser 60, which can beprovided to the treating chamber 16. The siphon break 108, in fluidcommunication with the inlet housing interior 168, provides for air tobe pulled into the water supply conduit 110 in the event that thepressure in the water supply conduit 110 drops below the pressure insidethe treating chamber 16, preventing any froth, foam, or soiled waterfrom the treating chamber to be siphoned into the water supply conduit110, preventing contamination of the water supply conduit or the watersupply itself. A blower 120 disposed within the blower housing 114 drawsair into the condenser 60 from the treating chamber 16 through the inletsection 100. The blower 120 operates to provide an airflow through thecondenser 60 such that the air drawn from the treating chamber 16 passesthrough the condensing passage 102, to the exhaust conduit 112, andthrough the blower housing 114 to the exhaust outlet 116. The blower 120can further provide additional ambient air into the exhaust conduit 112from external of the condenser 60 through one or more ambient air inlets122 adjacent the blower 120.

The inlet section 100 further comprises an inlet 130 providing fluidcommunication between the treating chamber 16 and the condenser 60. Theinlet 130 can comprise a vent 132 such that liquid or solid matter arefrustrated from entering the inlet section 100 of the condenser 60.

The water supply conduit 110 feeds an inlet housing 134 comprising acondensate outlet 136. Water, such as a household water supply can beprovided to the inlet housing 134 from the water supply conduit 110. Theinlet housing 134 can mount to the tub 14 to provide water to thetreating chamber 16 of the dishwasher 10 through the condensate outlet136. Additionally, the condensed liquid from the condenser 60 can beprovided to the treating chamber 16 through the condensate outlet 136,such that the condensate outlet 136 and the water inlet are integratedinto a single unit.

The blower 120 is disposed within the blower housing 114 and can bedisposed on the top of the blower housing 114. Alternatively, the blowercan be disposed on the sides or bottom of the blower housing 114, suchthat the blower 120 can be used to both introduce ambient air into theblower housing 114 as well as draw air from the treating chamber 16 andthrough the condenser 60.

Alternatively, the inlet 130 and the condensate outlet 136 can have avalve to selectively permit air or liquid to pass through them. Forexample, the inlet 130 and outlet 136 can have a rubber or poweredflapper that permits one-directional flow of air or fluids, preventingany unwanted backflow during wash and rinse operations. In alternativeexamples, any type of valve or mechanical seal can be utilized toselectively open and close the inlet 130 and outlet 136 or to permitunidirectional flow through them.

Turning to FIG. 5, a cross-sectional view of the condenser 60 bestillustrates an interior 142 of the condenser 60. The inlet section 100can further comprise an arcuate water wall 144. The water wall 144 isdisposed adjacent to the bottom of the inlet 130 such that any liquidsplashing into the inlet section 100 can drain back into the treatingchamber 16 through the inlet 130 without falling into the interior 142of the condenser 60. Two separator walls 146 disposed at the junctionbetween the inlet section 100 and the condensing passage 102 divide thecondenser 60 into a left conduit 148 and a right conduit 150. The leftand right conduit 148, 150 can be best appreciated by the airflow pathsillustrated in FIG. 7.

The condensing passage 102 can comprise curved walls 152 and angledwalls 154 disposed therein. The angled walls 154 mount to the sides ofthe condenser at a junction 155 and are slightly declined at an angletoward the center of the condensing passage 102. The angled walls definea pass 156 formed by the angled walls 154 within the interior 142. Thecurved walls 152 are spaced from the ends of the angled walls 154, suchthat each angled wall 154 has a complementary curved wall 152. Thecurved walls 152 define a turn 158 within the interior 142. Thecombination of the passes 156 and the turns 158 can define the left andright conduits 148, 150 throughout the interior 142, which define aserpentine path through the condenser 60.

The first and second ambient air inlets 104, 106 are disposed beneaththe junctions 155 of the first and second angled walls 154 at the top ofthe condenser 60. The first ambient air inlet 104 is disposed on theright side of the condenser 60 and the second ambient air inlet 106 isdisposed on the left, as illustrated. As such, both the left and rightconduits 148, 150 are in fluid communication with the ambient air. Itshould be appreciated that the position and number of the ambient airinlets 104, 106 is exemplary. More ambient air inlets are contemplatedand can be positioned at any position on the condensing passage 102,such that the interior 142 is in fluid communication with the ambientair.

A lower wall 160 is disposed below the bottom-most angled wall 152 anddefines a drip aperture 162 between the end of the bottom-most curvedwall 154. A turning wall 164 is disposed below the other walls,comprising half of a curved wall 152 for turning the left and rightconduits 148, 150 toward the exhaust conduit 112.

The inlet housing 134 further comprises a drip inlet 166. The inlethousing 134 can further comprise an inlet housing interior 168 in fluidcommunication with the interior 142 of the condenser 60 through the dripinlet 166. The interior 142 and the inlet housing interior 168 arefurther in fluid communication with the area external of the condenser60 through the siphon break 108.

Turning to FIG. 6, a close-up view illustrates the inlet housinginterior 168 separated into a siphon area 170, an inlet area 172, and anoutlet passage 174. An upper wall 176, a shared wall 178, the condenserwall at the siphon break 108, and a middle wall 180 define the siphonarea 170. The upper wall 176 further comprises two extensions 182extending into the siphon area 170. The siphon area 170 is in fluidcommunication with the condenser interior 142 through the drip inlet 166and external of the condenser 60 through the siphon break 108. The endof the upper wall 176 adjacent to the shared wall 178 also comprises oneextension 182 defines the drip inlet 166.

The inlet area 172 is defined by the middle wall 180, the shared wall178, and a bottom wall 184. The inlet area 172 is in fluid communicationwith the siphon area 170, the water supply conduit 110, and a water trap186. As such, any liquid or water pumped from the water supply conduit110 to the water trap 186 will pass through the inlet area 172. Themiddle wall 180 further comprises a set of two extensions 188. Theextension 188 nearest to the shared wall 178 defines a drip channel 190providing for fluid to fall from the drip inlet 166 into the inlet area172 where it can flow to the water trap 186.

The outlet passage 174 is disposed below the inlet area 172 on theopposite side of the water trap 186. The water trap 186 can be furtherdefined by a trap wall 192 and a water inlet wall 194. The outletpassage 174 is defined by the bottom wall 184, the trap wall 192, apassage wall 196, and the shared wall 178, providing fluid communicationbetween the water trap 186 and the condensate outlet 136.

It can be appreciated that the interior 142 of the condenser is in fluidcommunication with the condensate outlet 136 through the drip inlet 166,the siphon area 170, the inlet area 172, and the outlet passage 174.Furthermore, the water inlet conduit 110 is integrated with the interior142 of the condenser 60 at the inlet area 172, such that the condensedliquid from the condenser 60 and the water supply are integrated intothe same condensate outlet 136 to provide both a water supply andcondensed moisture from the condenser 60 to the treating chamber 16.

Turning to FIG. 7, the operation of the condenser 60 can be describedand the flow of air within the condenser can be appreciated. A humidairflow 210 draws into the condenser inlet section 100 through the inlet130 from the treating chamber 16. The airflow initially is directedupward in order to turn around the water wall 144, such that anysplashing or dripping water can return into the treating chamber 16through the inlet 130. A condensing airflow 220 moves into the interior142 of the condensing passage 102, being separated into two flow pathswithin the left conduit 148 and the right conduit 150. A first ambientairflow 222 is introduced into the airflow in the right conduit 150,mixing the humid airflow with the ambient air to reduce overallhumidity. A second ambient airflow 224 is integrated with the flow inthe left conduit 148, mixing the ambient air with the humid air toreduce overall humidity in the left conduit 148. As such, the air movingwithin the interior 142 downstream of the ambient air inlets 104, 106comprises a mixed airflow 226.

The mixed air 226 in both conduits 148, 150 draws through the serpentinepath of the interior 142 defined by the curved walls 152 and the angledwalls 154. As the humid air 210, the condensing airflow 220, and themixed airflow 226 flows through the interior 142, the air will condenseon the walls of the condenser 60 into a liquid. The liquid can drip downthe walls until reaching the bottom angled wall 154, where the liquidwill drip through the drip aperture 162 and into the inlet housinginterior 168 of the inlet housing 134 through the drip inlet 166. Withinthe inlet housing 134, the dripping liquid can flow into the water trap186 where it can flow back into the treating chamber 16 through thecondensate outlet 136 for removal from the system by the drain pump 44,for example.

The siphon break allows for air to be drawn into the water supplyconduit 110 if the pressure in the water supply conduit 110 drops belowthe pressure inside the treating chamber 16, which can otherwise drawfroth, foam or soiled water from the treating chamber 16. Additionally,any air flowing into the water supply conduit through the inlet housinginterior 168 can be drawn from the siphon break airflow 230. As such, awater flow 232 can be provided through the water supply conduit as awater supply 234, which is provided to the water trap 186. As water isadded to the water trap 186 from the water flow 232, a flow of spilledwater 236 from the water trap 186 spills into the outlet passage 174where the spilled water 236 can flow into the treating chamber 16through the condensate outlet 136. It should be appreciated that thewater trap 186 further provides protection from any humid air or steamescaping from the treating chamber 16 through the condensate outlet 136from passing into the interior area of the chassis 12 through the siphonbreak 108. Any such steam or humid air escaping form the treatingchamber 16 will condense into the liquid within the water trap 186.Thus, the amount of plastic wrapping or water proofing for componentswithin the chassis 12 is minimized.

External of the inlet housing 134, the mixed air 226 flowing from theinterior 142 of the condenser 60 can pass into the exhaust conduit 112as an exhaust airflow 228. The blower 120 can introduce additionalambient air 238 into the exhaust airflow 228 creating a mixed exhaustairflow 240. The mixed exhaust airflow 240 can be exhausted through theexhaust outlet 116 having an amount of humidity removed by the condenser60 as well as the overall humidity within the air reduced throughmultiple mixtures with ambient air.

A method for condensing moisture from moisture-laden air within thetreating chamber of the dishwasher can comprise passing themoisture-laden air through a condenser conduit and introducing ambientair into the condenser conduit at multiple locations along the condenserconduit. Passing moisture-laden air through the condenser conduit cancomprise drawing the humid air from the treating chamber and into thecondensing passage with the blower or drawing humid air from thetreating chamber and forcing it through the condensing passage. Themoisture-laden air can flow from the condensing passage to the exhaustconduit and out through the outlet. Introducing ambient air into thecondenser conduit at multiple locations along the condenser conduit cancomprise utilizing ambient air inlets to provide ambient air to thecondenser. Multiple ambient air inlets can be used to provide ambientair to the condenser conduit at multiple locations downstream of oneanother or at different passes of the condenser conduit.

It should be appreciated that the condenser as disclosed is beneficialin providing ambient air to the condenser from multiple sources alongthe condenser to mix with the humid air, reducing overall humidity ofthe air as well as simultaneously condensing the humidity from the airat the condenser walls. The ambient air feeds into interior of thecondenser at multiple positions to create mixed air as well as furthermixing with the mixed air downstream from the condenser at the blower tofurther reduce the overall humidity of the air before exhausting the airfrom the system.

It should be further appreciated that the water inlet is integrated withthe condenser outlet, such that any liquid condensed within thecondenser is provided back into the treating chamber of the dishwasherthrough the water inlet for removal from the system, for example, by thedrain pump.

It should be further appreciated that water trap provides for preventingany steam or humid air which can escape from the integrated water inletfrom escaping through the siphon break which can soak internaldishwasher components or develop leakage which can damage areassurrounding the dishwasher unit. Any steam leaking through the waterinlet will condense in the water trap system and is prevented frompassing to the siphon break. Thus, the need for waterproofing protectionsuch as a plastic wrap for a sound blanket within the dishwasher isminimized or eliminated, saving manufacturing time and cost.

While the invention has been specifically described in connection withcertain specific embodiments thereof, it is to be understood that thisis by way of illustration and not of limitation.
